摘要
结合西安北至机场城际轨道项目,对渭北黄土塬区黄土(地基土)的基床系数进行了现场试验研究。根据K30平板载荷试验结果,探讨了黄土(地基土)水平和垂直向基床系数的取值及两者之间的比例关系,分析在不同深度处水平、垂直基床系数的空间分布特征,为项目提供了可靠的设计参数。
Combined with the project of inter-city rail from north Xi'an to the airport,the field test research on the subgrade coefficient of the foundation soil in Weibei loess tableland was carried out. According to the result of K30 plate loading test,this paper discussed the values of the horizontal and vertical subgrade coefficient along with the ratio between them,and analyzed the spatial distribution characteristics of the horizontal and vertical subgrade coefficient at different depths,which provided reliable design parameters for the project.
